Great Western Highway contractor named after months of disruption

The Great Western Highway at Victoria Pass is set for a major rebuild after months of disruption for local communities, businesses and freight operators, with Seymour Whyte appointed to deliver a new crossing at Mitchells Causeway.

Major construction is expected to begin in July, with the road scheduled to reopen in the second quarter of next year. The route has been closed since serious defects were identified at Mitchells Causeway, cutting a key link between the Blue Mountains and Central West and placing pressure on detour routes.

Following geotechnical investigations and an accelerated procurement process, Seymour Whyte has been selected to construct a new bridge structure over the existing Mitchells Causeway. The structure will be supported by deep piles anchored into stable bedrock, while the convict-built causeway beneath it will be stabilised as part of the works.

The NSW Government says the design will restore the connection while improving long-term resilience. The new crossing will also be capable of accommodating an additional lane in the future, which was not possible under the existing roadway.

Minister for Roads Jenny Aitchison says the closure has been difficult for families, businesses, freight operators and daily road users, but the Government would not pursue a temporary repair.

“The NSW Government will not apply a band-aid fix. We are building a new crossing designed to serve local communities and freight for the next 100 years,” she says.

The announcement comes alongside an expanded $20 million support package for small businesses affected by the closure. Grants for businesses experiencing financial hardship in Mount Victoria, Hartley, Little Hartley and Hartley Vale will increase from $10,000 to up to $25,000.

Support will also be expanded to eligible businesses in Lithgow, Oberon and Blackheath, with grants of up to $10,000 available.

Transport for NSW will continue public transport uplifts, including extra rail, coach and bus services, while work continues on the crossing and detour routes.
